Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed April 27, 1907. Serial No. 370,565.

To all whom it may concern:

Be it known that I, WVAL'rnn JOHNSON, a

citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Swings, of which thefollowing is a specification, reference being had therein to the accompanying drawings.

My invention relates to new and useful improvements in swings, and has for its object, among other things, to produce a swing that can be readily manipulated and controlled by the party occupying the same, the chair moving in a substantially horizontal line, and which will be simple in design, of few parts so connected that the swing may be folded.

To these, and other ends, my invention consists in the swing having certain details of construction and combinations of parts as will be hereinafter described and more particularly pointed out in the claim.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures; Figure 1 is a side elevation of my improved swing complete and in operative position; F 2 is a similar view in its folded position; Fig. 3 is a front elevation; and Fig. 4 is an enlarged fragmentary view of the upper end of the chair bar.

In the practice of my invention I provide parallel rockers 11 which are rigidly connected by the cross bars 2 and the platform bars 3. The uprights 44 are secured at their lower ends to the opposite ends of said rockers by the bolts 5 having the thumb nuts 6 thereon and at their upper ends support the rod 7 which is held against endwise movement by the nuts 8. The radius of the arc of the circle forming the bottom edge of the rockers 11 is longer than the distance between the said bottom edge and the center of the rod 7. Suspended from the rod 7 are the chair bars 9which are connected at their lower ends by the rungs 10 and 11. The back of the chair is constructed with the side bars 12-12 which are united by the cross bars 13 having the slats 14 fixed thereto. Pivotally connected with the side bars 12 and chair bars 9 are the arm rests 15, and pivotally connected with said side bars 12 is the chair bottom 16. In one side of the bars 12 are the notches 17, and adjacent thereto are the swivel pins 18.

WVhen the chair is in its open position the rung l0 enters the notches 17 and the side bars 12 are secured thereto by the swivel pins 18, as shown in Figs. 1 and 3, in which position the chair bottom 16 rests upon the rung 11 and the arm rests 15 are in a substantially horizontal position.

To take down the chair the swivel pins are rotated, releasing the side bars 12 from the rungs 10 and then the side bars 12 are brought to a position parallel with the chair bars 9, as shown in Fig. 2, which is possible by reason of the swivel connection between the side bars and chair bottom, and the arm rests with the side bars and chair bars. Pivotally connected with the chair bars 9 are the posts 19 that are joined at their free ends to a chain 20 secured at its upper end to two of the uprights 4t, and at the lower end to a foot rod 21.

The swing is operated by the occupant placing his feet against the foot rod 21, and during the backward movement of the chair, pressing against said foot rod, and removing this pressure during the forward movement thereof. The chair swings upon the rod 7 and at the same time the whole frame rocks upon the rockers 1, giving a double motion and a substantially horizontal movement to the chair, thereby eliminating the fainting feeling that comes in a swing hung in the usual manner and rising and falling during its movement.

In Fig. 1 I have shown by broken lines a portion of my swing when the same is in its forward position.

The length of the chain 20 below the posts 19 may be varied by hitching the chain upon the hooks 22 fixed to said chain and allowing a portion thereof to hang loose.

To reduce to a minimum the friction upon the rods 7, and to eliminate as far as possible wear upon the chair bars 9, the bolts 23 are provided, which pass through said chair bars 9 and the apertures 24 therein and rest upon the rod 7, as shown in Fig. 4.

The swing is taken down and folded by releasing two of the uprights 4 from the rockers 1, that is, by unscrewing the nuts 6, after which the parts are folded, as shown in Fig. 2, in which condition it is quite compact in form and can be readily transported.

There are many minor changes and alterations that can be made within my invention. aside from those herein suggested, and I would therefore have it understood that I upper 'ends byrod IlOGfitGClJLt J distance do not limit myself to theexact constru'etionffthe"circle of which the rockers are an arc; herein shown and described, but" claim-all a chair suspended ZEIOIH said rod and movthat falls fairly within the spirit and scope able thereon; companion flexible members of my invention. fixed at one end to the uprights in rear of Having described .my invention, what T "said" chair, and between their ends to a part claim as new, and desire to secure by Letters upon said chair; and a foot rest rodsup= Patent, is
